Is there a command to add an mail alias to a user using zmporv? I'm in the process of migrating 800+ users to zimbra from our existing Mercury/Pegasus mail system. I have setup zimbra using the Split DNS guide on the wiki. My problem is that the merucy mail server does not allow the redirection of mail for individual users like i can perform in Zimbra with the zmprov ma <account> zimbraMailTransport. To work around this I have created an additional domain on the ZCS server and assigned an alias to users as they are migrated. I then create a forward file on the Mercury Server for the migrated user and mail is forwarded to the Alias address. Once all the users are migrated I will remove the aliases and delete the additional domain. I was hoping that there was a way that I could bulk provision the mail alias for all the users that I have already created, in order to save time. Otherwise I would manually have to edit each user account.
